JOHN W. HUDSON, OF WELLINGTON, ILLINOIS.

WHEEL-CULTIVATOR.

SPECIFICATION formingpart of Letters Patent No. 229,534, dated July 6,1880.

Application filed March 19, 1880.

To all whom it may concern:

Be it known that I, JOHN W. HUDsoN, of Wellington, in the county ofIroquois and State of Illinois, have invented certain new and usefulImprovements in Wheel-Cultivators; and I do hereby declare the followingto be a full, clear, and exact description of the invention, such aswill enable others skilled in the art to which it appertains to make anduse the same, reference being had to the accompanying drawings, and toletters of reference marked thereon, which form a part of thisspecification.

The nature of my invention consists in the construction and arrangementof a corn plow or cultivator, as will be hereinafter more fully setforth.

In the annexed drawings, to which reference is made, and which fullyillustrate my invention, Figure 1 is a plan View of my cultivator. Fig.2 is a side elevation thereof, showing the plows in the ground. Fig. 3is a similar view, showing the plow-beams elevated. Fig. 4 is a frontview of the machine. Figs. 5, 6, 7, 8, 9, and 10 are detailed views ofparts thereof.

A represents the arched axle, provided upon each end with the wheel B,and having the tongue 0 secured to its center.

From each side of the tongue extend two braces, a. a, one of whichconnects with the inner end of the spindle, while the other connectswith a flanged plate, E, that is placed on the spindle, and forms acovering for the inner end of the wheel-hub.

Upon each spindle or end of the axle is placed a sleeve, D, to which theplow-beams are coupled by means hereinafter described. At the outer endof the sleeve it is provided with a downwardly-projecting arm, F, and atthe top of this arm there is a slot or opening in the sleeve to receivethe spring G.

The spring has a slot in one end, which catches on a pin, 11, in theaxle. The spring is then wound around the axle sufficiently to give itthe desired tension. The other end of the spring has also a slot, whichis passed over a plate or bar, d, attached to the side of the arm F, anda pin, 0, passing through either one of a number of holes in said bar,holds the spring thereon.

(No model.)

The bar at is connected with the upright clevis I, which is suspendedfrom the doubletree or evener H, pivoted on the tongue.

When the plow strikes hard ground the team pulls the levers or arms Fforward, overcoming the power of the spring and throwing the plowsdeeper into the ground; and when the plow strikes mellow ground thedraft is lighter and the tension of the spring is relaxed, and then theplows will not run so deep.

The sleeve D is provided with longitudinal ribs :0 00, over which isplaced the C-shaped yoke J, forming the forward part of the coupling.This yoke can be moved out or in on the sleeve, as required, to set theplows the proper distance apart to suit the corn by loosening one of theset-screws or bolts that fasten the boxingf, as shown in Fig. 3.

K K are the plow-beams, connected at their forward ends by two bolts, hh, which pass through them, and also through an intermediate plate, L,which forms the rear part of the coupling. This plate is serrated onboth sides, and the extreme forward ends of the plow-beams arecorrespondingly serrated. The rear bolt, h, acts as a pivot foradjusting the beams, while the front bolt works in a slot in the plate,and when tightened the serrations hold the beams from slipping.

The front end of the plate or casting L forms two prongs, which areplaced between the two arms of the yoke J, and a rod, 2', passed throughthe whole, thus completing the coupling.

On the rod '5, between the prongs of the plate L, is placed a collar, M,which is fastened by a set-screw to the rod. By this means theplow-beams can be adjusted up or down, as required.

N N represent the shovels, which are constructed as shown in Fig. 5, thepoint being considerably wider than the body, as seen at 3 therebyallowing the loose dirt to fall back into the furrow from the shouldersof the shovel. The shovel is fastened to the beam by means of a block,0, and clip P, the shovel being hinged at the lower end of the block andfastened at the top by a break-pin.

For cultivating corn the shovels are removed and a share, R, is attachedto each pair of plow-beams, one working right and the other left. Thetwo pairs of plmv-bemns are R, PM] 1', and collar M, substantially asand then to be connected by :1 spring, h, for the lot the purposesherein set, forth.
